The system relies on fragile regular expressions to parse command structures; while it attempts to intercept dangerous operations, it fails to account for standard Shell command substitution syntax (specifically $(...)and backticks ...). An attacker can construct a command such as git log --grep=\"$(malicious_command)\", forcing Syntx to misidentify it as a safe git operation and automatically approve it. The underlying Shell prioritizes the execution of the malicious code injected within the arguments, resulting in Remote Code Execution without any user interaction."}, {"lang": "es", "value": "El m\u00f3dulo de autoaprobaci\u00f3n de comandos de Syntx contiene una vulnerabilidad cr\u00edtica de inyecci\u00f3n de comandos del sistema operativo que hace que su mecanismo de seguridad de lista blanca sea completamente ineficaz. El sistema se basa en expresiones regulares fr\u00e1giles para analizar estructuras de comandos; si bien intenta interceptar operaciones peligrosas, no tiene en cuenta la sintaxis est\u00e1ndar de sustituci\u00f3n de comandos de Shell (espec\u00edficamente $(...) y acentos graves ...). Un atacante puede construir un comando como 'git log --grep=\"$(malicious_command)\"', lo que obliga a Syntx a identificarlo err\u00f3neamente como una operaci\u00f3n git segura y aprobarlo autom\u00e1ticamente. La Shell subyacente prioriza la ejecuci\u00f3n del c\u00f3digo malicioso inyectado dentro de los argumentos, lo que resulta en ejecuci\u00f3n remota de c\u00f3digo sin ninguna interacci\u00f3n del usuario."}], "lastModified": "2026-04-08T16:01:38.553", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:orangecat:syntx:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C007E1E0-65F2-4954-BCEC-CD58C6C23CA6", "versionEndIncluding": "2.5.0"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
